为了确定油的性能和发动机的磨损.对使用中的润滑油进行监测一直是常用的方法.金属元素的分析尤为有益,因为磨损生成物通常是金属屑,某些添加剂也包括这些元素.磨损产物可以通过铁谱技术,由光学显微镜直接观察到.另一种方法是将这些生成物溶解,然后用油液光谱分析将其与其他金属元素一起进行定量,也可以使用原子光谱分析,例如原子发射光谱仪.在用油中的硫和磷等其他重要元素,可以用X射线荧光光谱仪监测.作为预知维修程序的一部分,这些技术的组合可以监测发动机及其润滑油系统中所采用的大部分元素,并监视其含量的变化.当任何一种金属或金属化合物的含量变得非常高时,表明一个或几个零件严重磨损;而当其他元素含量较低时,则表明油中添加剂损耗了,可由此得到警告.润滑油的红外(IR)分析也已应用多年,但将红外光谱仪用于对油液成分、油分解产物和污染物的定期监测则还不广泛.这其中有许多原因、首先,老式的分散式光谱仪采集一个在用油的谱图需要几分钟,这对一个每天要分析几百个油样的实验室来讲,其通过能力的低下是无法接受的.现
In order to determine the performance of the oil and the wear and tear of the engine, it has long been a common practice to monitor the lubricating oil in use.The analysis of metal elements is particularly advantageous because the wear products are usually metal shavings, and some additives also include these elements. Can be directly visualized by optical microscopy by ferrography, another method is to dissolve these products and then quantify them with other metal elements by oil spectroscopy, or by atomic spectroscopy such as atomic emission Spectrometers. Other important elements such as sulfur and phosphorous in the oil can be monitored by X-ray fluorescence spectrometry. As part of a predictive maintenance program, a combination of these techniques monitors most of the elements used in engines and their lube systems, And monitor its content changes.When the content of any one metal or metal compound becomes very high, indicating one or several parts of the serious wear and tear, and when the other elements are low, it shows that the oil additives loss, by This is warned.Rolume oil (IR) analysis has also been used for many years, but the infrared spectrometer for the oil composition, Regular monitoring of decomposition products and contaminants is not widespread, for a number of reasons, first of all, the old decentralized spectrometer takes a spectrum of oil in use for a few minutes, an analysis of hundreds of oil samples a day Laboratory, its ability to pass the low is unacceptable
